SN350 Base Oil for Industrial Lubricant Applications

What Is SN350 Base Oil?

SN350 Base Oil is a Group I mineral base oil produced from crude oil using solvent refining technology.
Compared to lighter grades such as SN150, Base Oil 350 features a higher viscosity, making it suitable for lubricant formulations that require stronger oil film strength and improved load-bearing performance.

The designation SN (Solvent Neutral) reflects the refining method, while 350 indicates its position in the medium-to-heavy viscosity range within Group I base oils.

Production Process of SN350 Base Oil

SN350 Base Oil is manufactured through a controlled refining sequence designed to enhance stability and performance:

1. Atmospheric and Vacuum Distillation
   Crude oil is separated into fractions, including a heavier lubricating oil cut.

2. Solvent Refining
   Aromatic compounds and unstable molecules are removed to improve oxidation resistance.

3. Dewaxing
   Wax reduction improves flow behavior at lower temperatures.

4. Hydro Finishing
   Final treatment enhances color, odor, and chemical stability.

5. Viscosity Grading
   The refined base stock is classified as Base Oil 350 based on viscosity parameters.

Key Applications of SN350 Base Oil

SN350 is selected for applications where higher viscosity and stronger lubrication film are required.

Typical uses include:

• Industrial lubricants

• Gear oils (light to medium duty)

• Hydraulic oils for heavy systems

• Grease manufacturing

• Compressor oils

• General machinery oils

Its higher viscosity allows better protection under moderate to heavy loads, especially in continuous industrial operations.

SN350 vs Other Base Oil Grades

SN350 vs SN150

• SN150 focuses on flow and light-duty applications

• SN350 provides enhanced film thickness and durability

SN350 vs SN500

• SN500 is heavier and designed for extreme pressure conditions

• SN350 offers a balance between protection and pumpability

Base Oil 350 is often chosen when SN150 is too light and SN500 is unnecessarily heavy.

Advantages of SN350 Base Oil

• Stronger oil film for improved wear protection

• Suitable for heavier industrial applications

• Good compatibility with additive systems

• Stable performance under continuous operation

• Cost-effective alternative to very heavy base oils

These characteristics make Base Oil 350 a reliable choice for industrial lubricant formulations.

Packaging & Supply Options

SN350 Base Oil is supplied in various packaging formats, including:

• Steel drums

• IBC tanks

• Flexitanks

• Bulk cargo

Depending on logistics and order volume, Basekim sources Base Oil 350 through supply channels in Turkey and the UAE, providing flexibility in origin and delivery terms.
